How to remove Tiles from the Windows 8 start screen

Hello,

I am using Windows 8. Every time I switch on my notebook, I see Tiles. But most of it are not used by me and I do not want to see them. Is there anyway I can remove them. Or, can I remove all the tiles and use a normal screen (ie, without tiles)?

Thank you for the reply. I have another question on tiles -->
There is a news tile. This tile shows news or headlines for the day. At home this tile do not show any news item. But when I take the notebook out of the city, ie, to some other city, I am able to see headlines. I do not know why I am not able to see news headlines in the news tile at home. If anybody know the answer, please reply. Thanking you in advance.

No, I am using one internet connection always. However, when I went out of the state, News showed without using any internet connection. All I did was activated wifi. Later I used 3 different connections and it still worked. Returning back home, it does not show anything. Thanx for early reply.
